Archaeologists found the tomb at the Carn Menyn site in Wales, generally thought to be the quarry for the so-called “bluestones” used for the inner circle of Stonehenge in 2300 BC.

The tomb is a passage grave, a cigar-shaped enclosure of stone that was once covered in earth. The tomb is in ruins and was looted in antiquity. Some organic material has been found and this will be carbon dated. Passage graves were common for elite members of society in the Neolithic.

The tomb was set atop a henge, a circular ditch and embankment that had a pair of bluestones are set upright at one end, reminiscent of the pairs of bluestones at Stonehenge.

It’s a mystery why the builders of Stonehenge would choose to drag stones weighing two to four tons more than 150 miles. One of the archaeologists investigating the site suggests that Carn Menyn, shown to the right, had religious significance because of the many natural springs in the area. The presence of the henge and tomb suggest the place did indeed have religious and cultural importance.
